If you want to replace the special characters with their normal correspondents, I use this function:

function limpaString($str) { 
    $str = preg_replace('/[áàãâä]/ui', 'a', $str);
    $str = preg_replace('/[éèêë]/ui', 'e', $str);
    $str = preg_replace('/[íìîï]/ui', 'i', $str);
    $str = preg_replace('/[óòõôö]/ui', 'o', $str);
    $str = preg_replace('/[úùûü]/ui', 'u', $str);
    $str = preg_replace('/[ç]/ui', 'c', $str);
    return $str;
}
